as my Swedish skills are still underdeveloped and I would sound like a 3 year old, if I would use them, I appologize to write in English - hope this is acceptable - for your and my comfort

As I have lived for four years in Sweden (Täby), my work contract came to an end last December and I had together with my family to move back to Germany. Since then we still have a vital link to Sweden and we will mantain that with various trips to there during the year.
Beside of meeting friends and other things, it is also off-roading which is just fabulous in Sweden. Inspired by off road meetings from Jeep Club Sweden, the SOT, which I attendend now three times as also various weekends at offroad clubs I enjoyed, I need to have a permanent vehicle availiable in Sweden.
Luckily I already own a Swedish registered Jeep Cherokee XJ, which I'll bring back to Sweden at påsk and hence, here is my problem:
Where to park my Jeep permanently at a safe and weather protected place?
So my objective and question to you is where hire a dry place for my Jeep, preferably with electricity to just buffer the battery for an affortable monthly amount of money.
I checked some commerical offers, but these are mostly downtown Stockholm and pretty expensive. As Arlanda is my typical point of arrival in Sweden, somthing in a 45min taxi drive distance from there would be great.
So, poor Offroader is seeking a place to park his rig permanently at a safe and roofed place in the North of Stockholm area for occasional Sweden visits during the year.
Offers are welcomed

This does not necessarily mean a place to fix things - just to park.
To get a face to this topic, that is me fixing the exhaust at Gröndal at last SOT at my other Jeep XJ

and as I promised a face to the personasking for support. We might have already met....

Looking forward to relpies or proposals
Regards
Jochen
